#663 closed System Defect (fixed)

UK wireless channel 12 not detected by Network manager

Reported by: Dante77 Owned by: kris
Priority: major Milestone:
Component: Network Manager Version: 9.1-RC1
Keywords: Network Manager Wireless SSID Channel Cc: trac-bugs@…


In the United Kingdom, routers can broadcast on channels 12 and 13.

However in the Network Manager the country is automatically set to US and will not see the SSID of my router.

I have tried to use ifconfig to change the country setting to GB (Great Britain) however a "Device Busy" reply is received.

Btw thanks for the addition of "hidden network" button on the Network Manager!

I think I should have mentioned that when my router is set to channels 12 or 13 then the SSID is not detected via the Network Manager, but when I configure the router to use channel 11 then there is no detection problem (although the signal quality would be better on channel 12, 13).

Thank you

I had this problem with my old Dell WiFi? card (3945ABG I think)

I edited /etc/rc.conf so that the country was set at boot by changing a line from:

ifconfig_iwn0="SYNCDHCP WPA"


ifconfig_iwn0="SYNCDHCP WPA country gb"

However, maybe the network manager could do with a box for "extra initialisation string", like in the old modem days, which would be added to ifconfig args, or even a specific field for WLAN country.

I have to say that I really struggled to get my Dell card to work in GB mode due to Dell Wifi firmware issues.

  • Resolution set to fixed
  • Status changed from new to closed

Thanks for the heads up, fixed in current and MFC'd to 9.1-RC3. You now have a "country" option under the wifi advanced tab, letting you select from the list of available countries to use.
